基于虚拟社会生态学模型的青少年虚拟世界融入量表编制及信效度分析

Development of virtual world integration scale for adolescents based on virtual social ecology model and its reliability and validity

目的在虚拟社会生态学模型的框架下编制青少年虚拟世界融入量表并检验其信效度。方法2023年3月至10月在武汉市、咸宁市抽取四所中学2543名学生作为研究对象。通过半结构化访谈、文献回顾、头脑风暴、德尔菲专家咨询法确定量表初步条目。对量表采用临界比值分析、同质性检验、验证性因子分析、效标关联效度检验、Cronbachα系数和分半信度进行信效度分析。结果(1)初步确定量表由10个维度20个条目组成,包括虚拟自我认同、情感互动、虚拟社交、网络霸凌、社群活动、价值认同、社区参与、社区管理、网络文化、虚拟社会资本。(2)项目分析中同质性检验的相关系数在0.496~0.767之间(P<0.001),临界比值分析差异有统计学意义(CR=21.897~53.546,P<0.001)。效度分析中的验证性因子分析模型拟合度为:CFI=0.933、NFI=0.951、IFI=0.927、RMSEA=0.064;效标效度均呈显著性正相关(r效标=0.450~0.855,P<0.01)。信度分析中总体Cronbachα系数为0.929,分半信度系数为0.846,各层面的Cronbachα系数在0.719~0.900之间,分半信度系数在0.729~0.913之间。结论虚拟世界融入量表具有较好的信效度,可作为青少年虚拟世界融入程度的评价工具。

Objective To develop a virtual world integration scale for adolescents and test its reliability and validity within the framework of the Virtual Social Ecology Model.Methods A total of 2543 students from four schools in Wuhan and Xianning were recruited from March to October 2023.The preliminary items of the scale were determined by semi-structured interview,literature review,brainstorming and Delphi expert consultation.The compiled scale was analyzed for validity and reliability using critical ration analysis,homogeneity test,confirmatory factor analysis,correlation related validity test,cronbachαcoefficient,and split-half coefficient.Results The scale was preliminarily determined to consist of 20 items in 10 dimensions,including virtual self-identity,emotional interaction,virtual social interaction,cyber bullying,community activities,value identity,community participation,community management,network culture and virtual social capital.In the item analysis,the correlation coefficient of homogeneity test ranged from 0.496 to 0.767(P<0.001),and there was statistical difference in critical ratio analysis(CR=21.897-53.546,P<0.001).The fits of the confirmatory factor analysis model in validity analysis were:CFI=0.933,NFI=0.951,IFI=0.927,and RMSEA=0.064.The criterion validity showed a significantly positive association(the coefficient was between 0.450 and 0.855,P<0.01).The overall Cronbachαcoefficient was 0.929 and the split-half coefficient was 0.846.The Cronbachαcoefficients of sub-questionnaires were between 0.719 and 0.900,and the split-half coefficients were between 0.729 and 0.913.Conclusion The Virtual World Integration Scale has good reliability and validity,and can be used as an assessment tool for the level of adolescents′integration in virtual world.
